A field experiment was conducted during 2017-2018 for evaluating the performance of brinjal (Solanum melongena L.) genotypes under foothill condition of Nagaland following randomized block design with three replications at the experimental farm of Horticulture, SASRD, Nagaland University, Medziphema, Nagaland. Forty six brinjal genotypes viz. IIVR- 1, IIVR-2, IIVR- 3, IIVR- 4, IIVR-5, IIVR-6, IIVR-7, IIVR-8, IIVR-9, IIVR- 10, IIVR-11, IIVR-12, IIVR-13, IIVR-14, IIVR-15, IIVR-16, IIVR-17, IIVR- 18, IIVR-19, IIVR-20, IIVR-21, IIVR-22, IIVR-23, IIVR- 24, IIVR-25, IIVR- 26, IIVR-27, IIVR-28, IIVR-29, IIVR-30, IIVR-31, IIVR-32, IIVR-33, IIVR- 34, IIVR-35, IIVR-36, IIVR-37, IIVR-38, IIVR-39, IIVR-40, IIVR-41, IIVR- 42, IIVR-43, IIVR-44, IIVR-45 and Nagaland Local (check variety) were evaluated for their growth, yield, quality and genetic attributes. High phenotypic coefficient of variation, genotypic coefficient of variation and high heritability coupled with high genetic advance was found for anthocyanin content, fresh weight of fruit, number of leaves plant-1, yield plant-1, fruit length and fruit diameter. The study on path analysis revealed that maximum positive direct effect on yield is exerted by fresh weight of fruit (1.08) and number of fruits plant-1 (0.407). Based on the experimental results, it can be concluded that, genotype IIVR-31 and IIVR-7 was proved to be potential yielder under foothill condition of Nagaland. SAARC J. Agri., 18(1): 13-21 (2020)

An investigation was carried out to study the effect of intercropping crops (knol khol and broad bean) on growth, physiological aspects and yield of Cabbage. Sole crop of Cabbage was grown and between the inter-row spaces knol khol/broad bean was intercropped in single/double row planting. Spacing of 60 x 30 cm between cabbage and 30 x 30 cm for knol khol and 30 x 20 cm for broad bean was adopted. Growth parameters were recorded for cabbage as sole crop and as intercropped with single/double row of knol khol / broad bean. Maximum fresh weight (376.80 g) and dry weight (45.10 g) of the plant were observed in cabbage as sole cropping at 75 DAT which is at par with cabbage intercropped with single row of broad bean with fresh weight (344.13 g) and dry weight (41.56 g). However, on complete analysis of the physiological parameters, it can be concluded that cabbage sole cropping, recorded highest harvest index (64%), net assimilation rate (0.0344 g m -2 day -1 ), plant growth efficiency (30.30%), crop growth rate (2.08 g cm -2 day -1 ), relative growth rate (0.0306 g g -1 day -1 ) except leaf area index in which cabbage intercropped with single row of broad bean (1.16), exhibited maximum. Superiority in physiological parameters like leaf area index (1.16) and harvest index (64.00 %) was recorded in Cabbage with single row broad bean and sole crop of cabbage, respectively. The maximum weight of the head (875.54 g), the maximum compactness (30.30) and maximum yield was found 48.2 t/ha in cabbage sole cropping (T 1 ) which remained at par with cabbage intercropped with single row (776.51 g) of broad bean (T 4 ), (29.78) and 44.71 t/ha. Remarkable variation was observed in the performance of cabbage intercropped knol khol and broad bean under Imphal west condition.

The research was conducted during the Rabi season of 2019-2020 on 32 genotypes of French bean (Phaseolus vulgaris L.) to evaluate genetic variability, correlation coefficient and path coefficient. The genotypes were studied for 13 different characters of growth and yield attributing characters in Randomized Block Design with three replications for each genotype. All characters recorded higher PCV value over GCV thereby indicating the influence of environmental factors in their expression. High heritability observed in all the characters studied and high heritability coupled with high genetic advance found in the parameters viz. number of pods per plant, average pod weight, 100 seed weight and pod yield per plant. Correlation coefficient analysis showed pod yield had significant and positive correlation with number of pods per plant, pod length, average pod weight and 100 seed weight. Path analysis revealed that maximum positive direct effect w.r.t pod yield per plant was brought about by the parameters viz. 100 seed weight, days taken to marketable maturity, number of seeds per pod, number of pods per plant, average pod weight, pod width and pod length hence, should be given more importance for genetic improvement to bring about an increase in overall production of french bean through enhanced pod yield per plant.
